In some cases, the tetrabod shape is broken during various processing or compounding steps, resulting in whiskers that break down into triaxial, biaxial, or uniaxial needle-like crystals.
（作 用）
本発明の複合強化材に用いる酸化亜鉛ウィスカーには次
の作用がある。(Function) The zinc oxide whiskers used in the composite reinforcing material of the present invention have the following effects.
第１は３次元構造のテトラボッド状酸化亜鉛ウィスカー
は３次元方向の等方的に配向するため、はぼ全方的に強
度を得て、他の補強用基材の一軸異方性が緩和もしくは
解消する（第２図参照）。First, the tetrabod-shaped zinc oxide whiskers with a three-dimensional structure are oriented isotropically in three dimensions, so they gain strength in almost all directions, and the uniaxial anisotropy of other reinforcing base materials is relaxed or (See Figure 2).
第２は各種処理や配合の段階でテトラボッド状ウィスカ
ーが折損して１軸になった針状結晶部は根元の径〉先端
の径へと減径するため根元と先端とでは回転応力が異な
り、全方的空間に配向し。Second, the tetrabod-like whiskers are broken during various processing and compounding stages, and the uniaxial needle-like crystal part decreases in diameter so that the diameter of the root is greater than the diameter of the tip, so the rotational stress is different between the root and the tip. Oriented in omnidirectional space.
他の補強用基材の一軸異方性を緩和もしくは解消する（
第３図参照）。Reducing or eliminating the uniaxial anisotropy of other reinforcing base materials (
(See Figure 3).
第３は１軸になった針状結晶部は根元の径〉先端の径へ
と減径するため先端方向へは抜は難く、他の補強用基材
が一軸同径により軸方向に抜は易いのと対照的に補強作
用を得る（第３図参照）。Thirdly, the diameter of the uniaxial needle-like crystal part decreases from the diameter of the root to the diameter of the tip, so it is difficult to remove it in the tip direction, and it is difficult to remove it in the axial direction because the other reinforcing base material is uniaxial and has the same diameter. In contrast to being easy, a reinforcing effect is obtained (see Figure 3).
このように本発明の複合強化材は第１〜第３の作用が奏
合されて、従来の複合強化材に見られた異方性を緩和も
しくは解消する作用がある。In this way, the composite reinforcing material of the present invention combines the first to third effects, and has the effect of alleviating or eliminating the anisotropy observed in conventional composite reinforcing materials.

４軸のものの一部が折損したものと考えられる。In this case, in the zinc oxide whisker, the needle-like crystal part has three axes,
There are cases where 2-shaft or 1-shaft parts are mixed in, but this is thought to be due to a part of the 4-shaft part being broken.

ではない。On the other hand, simple needle-shaped zinc oxide whiskers can also be produced, for example, by firing metal zinc powder at the same time as charcoal, etc., to produce them on the wall of a crucible, etc., but this is not suitable for mass production.

発生し、強度や加工容易性が低下する。Next, regarding the zinc oxide whisker shape, if it is too small, it will not be possible to ensure the strength as a composite reinforcing material, and the ease of processing will also decrease. On the other hand, if it is too large, problems will occur in terms of dispersion, and strength and ease of processing will decrease.
