玻纤增强塑料比重小,它的比强度超过铝合金而与高合金钢相仿,因此我国俗称玻璃钢,沿用迄今似已成为正式命名。但随着高强度、高模量纤维的相继问世,如硼纤维、碳纤维、石墨纤维、芳香聚酰胺纤维(即Kevlar-29、Kevlar-49)等,它们与塑料复合后的机械强度,有的还超过钢材。我们只能称之为纤维增强塑料,不能也叫玻璃钢,因为这类材料中并无玻纤成份在内。同时我国所称的玻璃钢,一般指玻纤增强热固性树脂,如增强聚酯树脂、环氧树脂、酚醛树脂、呋喃树脂、DAP(聚邻苯二甲酸二烯丙基酯)树脂等而言,对玻纤增强热塑性塑料,如增强聚烯烃、尼龙、聚甲醛、聚碳酸酯、聚砜等,一般又称之为工程塑料,不称
The proportion of glass fiber reinforced plastic small, its strength than aluminum alloy and high alloy steel similar, so commonly known as glass fiber reinforced plastic in our country, so far has become the official name has become. However, with the high strength, high modulus fibers have come out one after another, such as boron fiber, carbon fiber, graphite fiber, aromatic polyamide fiber (ie Kevlar-29, Kevlar-49), their mechanical strength after plastic compound, More than steel. We can only call it fiber reinforced plastic, can not be called FRP, because there is no fiberglass composition in such materials. At the same time, the so-called FRP generally refers to the glass fiber reinforced thermosetting resin, such as reinforced polyester resin, epoxy resin, phenolic resin, furan resin, DAP (poly diallyl phthalate) resin, etc., Glass fiber reinforced thermoplastics, such as reinforced polyolefin, nylon, polyacetal, polycarbonate, polysulfone, etc., also known as engineering plastics, not
