Laser Machining Fiber-Reinforced Plastics
Fibre-reinforced plastic (FRP) is a composite structural material containing high-strength fibrous embedded reinforcements which develop mechanical properties greatly superior to the base polymer (called 'matrix' in this context). The fibers are usually fiberglass, carbon, or aramid (a family

Polyimide composites challenge metals
preload. Here, a polyimide composite manufactured from a fiber-reinforced sheet-molding compound addresses the problem. Fiber alignment in SMCs is more random than in laminates made from plies of X-Y woven fabric. Because randomness increases the amount of Z-aligned fibers within the part, SMCs tend

Stronger and Lighter -- Composites Make Their Mark
one constituent is dissolved in another. Biological structural materials in nature including wood, bamboo, bone, teeth, and shell are all composites. Use of synthetic composite materials is not new. Bricks made from straw-reinforced mud are mentioned in the Old Testament. This material also has been

Composites lighten up A380 seats
To reduce the weight of aircraft seats, a major seat manufacturer switched several of its seating elements from aluminum to carbon-fiber-reinforced composites. Aircraft seating parts including lumbar and thigh supports, armrest table covers, and shields for in-flight video screens made of Tepex

More metal parts go to composites
such as high-performance composites made from polyimides, epoxies, fluoropolymers, and phenolics reinforced with woven, braided, or chopped graphite, carbon, glass, and aramid fibers. Advancements in these raw material forms provide designers a balance of price, processibility, and performance. For years

An Investigation of Pin Bearing Strength on Composite Materials (.pdf)
that the. ASTM D 953 bearing strength test can be very misleading and that actual connection details. should be mimicked in order to generate sound design values. Introduction. The design of connections, within Fiberglass Reinforced Polymer (FRP) structures, is one of the. most critical elements when

Laminated Plastics
and cloth-reinforced laminates are made with phenolics. Polyesters are used for both electrical and mechanical service requiring moderate heat resistance. The resins are usually mineral filled to improve dimensional stability and flame retardancy and to reduce cost. Malemine resins are used primarily
